[GitHub] [incubator-shardingsphere] liwu3230 opened a new issue #4345: Springboot+Jpa+sharding-jdbc 跨多表查询走结果归并后，返回的数据类型不是包装类而被转成有默认值的基本数据类型

图片中joinMsgTicketPmsMsgStatereport.get("result")对应的java类型是Integer,数据库字段类型为int（11），单表查询的时候如果查询结果中result字段为null，可以映射为null回来，但是如果是跨多表查询，走了结果归并的话，返回的会是0 ，这与直接执行sql的结果不一致，在很多业务场景中null是有意义的
